To configure static mapping (using the ip-address option) for an iSCSI initiator, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# iscsi initiator
ip-address 10.50.0.0
switch(config-iscsi-init)#
switch(config)# iscsi initiator
ip-address 2001:0DB8:800:200C::417A
switch(config-iscsi-init)#
switch(config)# no iscsi initiator
ip-address 2001:0DB8:800:200C::417A
To assign the WWN for an iSCSI initiator, follow these steps:
Command
Step 1
switch(config-iscsi-init)# static nWWN
system-assign
switch(config-iscsi-init)# static nWWN
20:00:00:05:30:00:59:11
Step 2
switch(config-iscsi-init)# static pWWN
system-assign 2
switch(config-iscsi-init)# static pWWN
21:00:00:20:37:73:3b:20
If the system-assign option is used to configure WWNs for an iSCSI initiator, when the configuration is
Note
saved to an ASCII file the system-assigned WWNs are also saved. Subsequently if you perform a write
erase, you must manually delete the WWN configuration from the ASCII file. Failing to do so can cause
duplicate WWN assignments if the ASCII configuration file is reapplied on the switch.
Making the Dynamic iSCSI Initiator WWN Mapping Static
After a dynamic iSCSI initiator has already logged in, you may decide to permanently keep the
automatically assigned nWWN/pWWN mapping so this initiator uses the same mapping the next time it
logs in.
You can convert a dynamic iSCSI initiator to static iSCSI initiator and make its WWNs persistent (see
"Dynamic Mapping" section on page
You cannot convert a dynamic iSCSI initiator to a static iSLB initiator or a dynamic iSLB initiator to a
Note
static iSCSI initiator.

Purpose
Enters configuration mode.
Configures an iSCSI initiator using the IPv4 address of
the initiator node.
Configures an iSCSI initiator using the IPv6 unicast
address of the initiator node.
Deletes the configured iSCSI initiator.
Purpose
Uses the switch's WWN pool to allocate the nWWN for
this iSCSI initiator and keeps it persistent.
Assigns the user provided WWN as the nWWN for the
iSCSI initiator. You can only specify one nWWN for
each iSCSI node.
Uses the switch's WWN pool to allocate two pWWNs
for this iSCSI initiator and keeps them persistent. The
range is from 1 to 64.
Assigns the user provided WWN as the pWWN for the
iSCSI initiator.
